CRBURETER.

SPECIFICATION forming part of Letters Patent N o. 669,157, dated March 5, 1901.

Application tiled October 27, 1900. serial No. 34,571.

"0 all whom, t may concern:

Be it known that. we, ROY F. CARTER and RICHARD W. ZIERLEIN, ci tizens of the United States, residing atSt. Louis, State of Missouri, have invented certain new and useful Improvements in Carbureters, of which the following is a full, clear, Aand exact description,

-reference being had to the accompanying drawings, forming a part hereof.

Ourinvention has relation toimprovements in carbureters or apparatus for manufacturing illuminating-gas; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure l isa vertical middie section of the tank and operating parts, a portion being shown in elevation. Fig. 2 is a horizontal section on line22of Fig. 1. Fig. 3 is a detail showing the manner of mounting the floats to the liioat-pipe. FigaI is a sectional detail on line 4 4 of Fig. 1, showing the cock in an open position for the free passage of a siphon-tube intended to be inserted into the equalizerpipe; and Fig. 5 is diagrammatic View showing the manner of coupling the device to the supply-barrel.

The present apparatus is an improvement on the carburetor described in United States Letters Patent granted to us under date of May l5, 1900, and numbered 649,435, the object in the present case being to qualify the construction therein set forth, with a view of simplifying the same and insuring better and more uniform result-s and with afurtherview of enabling the operator to fill the generator or tank while the process of carbureting is going on.

In detail the invention may be described as follows:

Referring to the drawings, 1 represents a closed tank or generator having at the bottom thereof an air-chamber 2, with which communicates an airsupply pipe 3, leading to an air-pu mp. (Not shown.) Projecting from the center of the bottom of the generatorisa guide-tube 1t, open at both ends, the lower end being in communication with the airchamber 2. Passed loosely about the guide tube 4 is a float-pipe 5, closed at the top and open at the bottom, said pipe 5 being slightly longer than the guide-tube 4. Depending (No model.)

in the hydrocarbon liquid in the tank (said liquid being any volatile hydrocarbon capable of generating gas) by the hollow cylindrical oats or tubes 10, secured to the pipe 5 and adjustable along the same by means of a set-screw 1l, passed through the Verticallyelongated slot 12 of a strip 13, secured tangentially to the walls of the floats, the screw being carried by the interiorly-screwthreaded bosses 14, carried by the float-pipe and disposed diametricallyat right angles to the deflected portions 6' ofthe tubes.

Leading from the air-chamber 2 and projecting through the roof of the tank is an equalizer-pipe l5, provided with an ordinary faucet valve or cock 16, well known on the market. Leading from the pipe l5, above the tank, is a shunt or branch pipe 17 terminating in a faucet Valve or cock 1S, the end of the pipe being adapted to be coupled to a hose leading to the bung-hole of a supplybarrel 19, in which the hydrocarbon is stored. Leading from the roof of the tank is a fillingtube 20, adapted to be coupled by a hose to the discharge-hole of the barrel, this arrangement rendering it possible to feed the tank while the process of carbureting is going onthat is to say, while the air from the air-pump is forced into the tank. By thus coupling the barrel to the pipes 17 20, as indicated, the pressure in the pipe 17 forces the liquid in the barrel against any accumulated gas-pressure in the tank 1. Leading from the base of the -filling-tube is the gas-delivery pipe 21, which leads to any source of consumption.

When it is desired to drain the chamber 2 of any waters of condensation which may have accumulated therein in course of time, the cock 16 is opened, Fig. 4, and a Siphon* tube inserted through the Valve and into the pipe 15 down to the bottom of the said chamber 2, the Waters of condensation being siphoned off in the well-known manner. In

fact, the airchamber 2 serves to condense IOO the greater portion of the moisture carried by the air-currents, which would otherwise be cond ucted into the tank and inj urionsly affect the illuminating qualities of the gas evolved from the hydrocarbon in the tank.

The float-pipe 5 is additionally guided in its` movements by the upper guide-pipe 22, projecting from the roof of the tank and closed at the top by a cap The upper end of the float-pipe is provided with a chain 251, whose lower end is secured to the said pipe and whose upper end is secured to the wall of theguide-pipe 22. This chain enables the operator to shake the float occasionally and disengage any foreign matter and air-bubbles which may tend to clog the free passages of the perforations iu the discharge-pipes 6' 7 S 9. Ot' course the chain is of suiicientlength to permit the tloat-pipe to oscillate within the limits made necessary by the variable depth of the liquid within the tank.

In order to better diffuse the hydrocarbon to the action of the air-currents, we provide the walls ot' the tank with a felt or other absorbent lining L, which by capillary attraction causes a portion oi' the liquid to be diffused in a sheet about the walls of the tank, and thereby become more susceptible to the disintegrating and evaporating action of the air admitted into the tank. Like in our patent referred to, the object of making the floats l0 adjustable along the float-pipe is to control and adj ust the depth or degree of subinergence ot' the perforated pipes 6 7 S 9 below the surface ot' the liquid, the adjustment depending, of course, on the speciiic gravity of the hydrocarbon operated on. The arrows in Fig. l indicate the course of the air-currents and that of the gas evolved from the liquid in the tank.

Having described our invention, what we claim is- I. In a carbureter, a closed tank or generator, an air-chamber below the same, a pressure-equalizer pipe having its lower end coniniunicating with the air-chamber, an air-supply pipe communicating with said air-chamber and with the interior of the tank, a [illingtube leading to the tank,the upper ends of the equalizer-pipe and iilling-tube being adapted to be respectively connected above and below the surface of the liquid of a suitable supplybarrel, a gas-delivery pipe leading from a point above the liquid in the tank, a guidetube leading from the air-chamber into the tank, a float-pipe playing loosely over the guide-tube, a tloat for said pipe, and depending tubes leading from the upper end of the iloat-pipe to a point below the surface of the liquid,the lower ends of said tubes being open to discharge air into the liquid, substantially as "set forth.

2. In a carbureter, a closed tank or generator, au air-chamber below the saine, an airsupply pipe leading to the air-chamber, a pressure-equalizer pipe leading from the airchamber to a point above the tank, a shunt or branch pipe leading from the equalizerpipe, a filling-tube leading from the top ol the tank, a gas-delivery pipe coupled to the base of the filling-tube, cocks at the upper ends of the equalizer-pipe and branch pipe, a

guide-tube leading` from the air-chamber into the tank, a float-pipe playing loosely over the gnide-tube, a float for said pipe, depending tubes leading from the upper end of the floatpipe to a point below the surface of the liquid, perforated air-dischargeI pipes connected to the lower ends oi? the depending tubes, an e terior guide-pipe for the lioatfpipe projecting' from the root' of the tank, and suitable floats adjustable along the Heatpipe, and a supply-barrel adapted to be coupled to the filling-tube and brauch pipe aforesaid, the parts operating substantially as and for the purpose set forth.

3. In a carbureter, a tank or generator, a float-pipe located therein, screwthreaded bosses carried by the peripheral walls of the pipe,hollow [ioats or tubes,strips secured tangentially to the walls of the floats, elongated slots formed inthe strips, and binding-screws passed through the slots and into the bosses, whereby the floats can be vertically adjusted along the float-pipe substantially as set forth.

In testimony whereof we at'iix our signatures in presence of two witnesses.
